Since the list seems quiet right now, thought I would ask a question.
Up till now I haven't really worried about the warp defconfig being up
to date since, realistically, the stock kernel was not usable on the
warp. Since it usually boots from NAND, the lack of an ndfc driver
made it unbootable in a production system.

However, the 2.6.29 kernel will boot, so the defconfig problem becomes
more acute. The problem is keeping the changes that are required for
the warp while also handling the normal changes that happen every
release.

For example, the current git diff shows CONFIG_SIMPLE_GPIO which is
just a new feature and can be safely left unset. But the watchdog made
it into the kernel, so CONFIG_PIKA_WDT should be set for a warp.

Any ideas for a good way of handling this?

Cheers,
   Sean

You can certainly send me patches for defconfig updates.  I go through
and update them all (via make xxx_defconfig; make oldconfig) after -rc2
is available, but I might not set everything exactly as you would want
to see it.

If there's a chicken/egg problem in that there are drivers or changes
that went upstream but aren't in the powerpc branches yet for one reason
or another, you can poke me about getting things pulled in.

Since I'll be doing defconfig updates today, just tell me which options
you need set or disabled.

Let's try this patch and see how it goes. If it doesn't apply easily, I
will just give you a list. 

Note a few of the options will be disabled with the make oldconfig and
that is fine.

The ones I know will be disabled are the PIKA_SD driver and the
PIKA_LEDS driver. Also I don't think it will let you disabled
SCSI_WAIT_SCAN :( You have to patch a Kconfig for that.

Cheers,
   Sean

OK, I'll work these in tonight and then send them Ben's way.
